This standard applies to protective helmets for industry where the helmet is intended to protect a static user frompredominantly falling hazards. A series of impact tests must be carried out using a xed head-form and a falling weight in order for a helmet tomeet this standard. WHAT IS EN 397? THERE ARE FOUR COMPULSORY ELEMENTS TO EN397 , IMPACT , PENETRATION , FLAMMABILITY AND ANCHORAGE

INDUSTRIAL HELMETS

CHECKYOUR DATES In accordance with EN 397, marking of the helmet should include the year and quater of manufacture. Period of obsolescence of the helmet and its components must be declared on the User Sheet which is delivered together with the helmet PW98, PW54, PW55, PW97, PW50, PW51, PW57 see pages 368 & 369 ALL PORTWEST SAFETY HELMETS MEET EN397

ANCHORAGE Helmets can only protect when retained on the head. EN 397 requires that either the helmet shell or the headband is tted with a chinstrap or with the means of attaching one, i.e. anchorage points.

FLAMMABILITY The helmet is exposed to a ame and it must not burn with ame emission more than 5 seconds after removal of the ame source.

IMPACT The Helmet must not allow more than 5Kn of energy to spread to the head after a fall of a 5kg weight from a 1 meter height. This test is performed at room temperatures of both +50 °C and -10°C.

PENETRATION The tip of the test mass used (3 kg from 1m height) must not come into contact with the skull. This test is also performed at a room temperature of +50 °C and –10°C.
